LP2975 Datasheet MOSFET LDO Driver/Controller

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LP2975 MOSFET LDO Driver/Controller September 1997 LP2975 MOSFET LDO.

General Description

A high-current LDO regulator is simple to design with the LP2975 LDO Controller.

Using an external P-FET, the LP2975 will deliver an ultra low dropout regulator with extremely low quiescent current.

High open loop gain assures excellent regulation and ripple rejection performance.
